Hey guys,
My motorcycle is known to have this problem where the ignition coil can fail in a way that sends a very high voltage spike through the electronics and damages the ECU. The repair costs thousands of dollars.
When I connect a scope to my bike's battery with the engine running, I see a constant 14V with occasional transient spikes to 40-70VDC. I believe this is normal for an automotive power system, but it got me thinking. Would it be possible to place a device in the bike's electrical system (across the battery?) that would absorb voltage spikes of this type as well as in the case of a coil failure? Perhaps some type of TVS diode? Where would the device have to be placed in order to protect the entire system?
Thank you
